Yamaroku's soy suaces are brewed with full-bodied taste & aroma

All Yamaroku soy sauce is made in wooden barrels called “Kioke” – the key to
delicious soy sauce. Microbes that live in the Kioke ferment the soybeans naturally,
giving the soy sauce a sweeter aftertaste.

sauce, Tsuru-bishio, is our ultimate pursuit
of depth, richness, and smoothness.
